particularly to a furniture connecting piece which has a gapped groove at
the position where a screw is contained in the furniture connecting
piece.

BACKGROUND OF THE INVENTION

[0002] Now, furniture with large volume is usually designed for assembly.
That is to say, furniture components are pre-processed according to the
shape and dimension of the future, during the transportation the
furniture components are first transported to the user, and then they are
assembled into combination with the help of furniture connecting pieces.
The methods not only resolve the inconvenient problems in the package and
transportation, but also benefit for the user to disassemble and keep
them when they are idled, this saves the store space.

[0003] Most of the present furniture fittings are designed as that a male
connecting piece and a female connecting piece are engagable with each
other, called furniture connecting piece. The male connecting piece has
protruding posts, and the female connecting piece has recesses matching

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

[0049] In order to concretely illustrate the technical solutions and
structure features of the furniture connecting piece of the present
invention, the follow will further illustrate with specific embodiments
and the drawings.

[0050] First, referring to FIG. 1, FIG. 8 and FIG. 10, FIG. 1 is a view of
the first embodiment of the furniture connecting piece of the invention,
FIG. 8 is a view of the second embodiment of the furniture connecting
piece of the invention, and FIG. 10 is a view of the third embodiment of
the furniture connecting piece of the invention.

[0051] The furniture connecting piece includes a base 110 and screws 140.
The base 110 has opposite upper surface 112 and lower surface 111,
opposite left and right surface 120, and opposite front surface 117 and
back surface 118(not show). The lower surface 111 of the base has gapped
grooves 150 extending to the upper surface 112 of the base. The gapped
groove 150 runs through the front surface 117 and the back surface 118 of
the base 110. The upper surface 112 of the base is provided with screw
holes 130 communicating with the gapped grooves 150, the screw 140 passes
through the screw hole 130 and is partially contained within the gapped
groove 150.

[0052] Referring to FIG. 3 and FIG. 4, the two side surfaces 120, the
front surface 117and the lower surface 118 of the base 110 are all
provided with chamfered teeth. When the furniture connecting piece is
installed into the predestined recess-cut in the furniture component, the
chamfered teeth increase the biting strength between the furniture
connecting piece and the furniture component, which further increase the
connection strength between the furniture component and the furniture
connecting piece.

[0053] Referring to FIG. 1 and FIG. 5, the upper surface 112 of the base
110 is provided with one or several protruding posts 113. The protruding
post 113 can be inserted into a mating recess in another furniture
connecting piece, thereby matching the two furniture connecting pieces.

[0054] Referring to FIG. 2 and FIG. 6, A plurality of blind holes 115 are
defined in the lower surface 111 of the base 110. If the connecting piece
is made of plastic materials, the plastic piece will shrank during the
injection molding process, thereby leading the connecting piece to
deform. However the blind holes can decrease shrink ratio of the
connecting piece and maintain the shape of the connecting piece. And,
before the connecting piece of the invention is installed into the recess
cut preset on the surface of the furniture parts, first it is to coat the
base 110 periphery with glue, then install the connecting piece into the
recess cut. It is to depend on the frictional force between the base 110
periphery and the wall of the recess cut and the adhesive force of the
glue to fix joint the base 110 and the furniture part. Because there are
a few blind holes 151 on the lower surface 111 of the base 110, a part of
the glue flows into the blind hole 151 and is kept in the connecting
pieces. When the connecting piece is installed into the recess cut in the
furniture, the glue will not flow out of the connecting piece for the
extrusion between the side surface of the connecting piece and the wall
of the recess cut, which promises the film thickness formed by the glue
and the adhesive force of the glue and then promises the adhesive
strength between the connecting piece and the furniture part. In the
present invention, the connecting piece s and the furniture part tightly
joint with high joint strength that is beneficial for the lifetime of the
modular furniture.

[0055] Referring to FIG. 7, the installation method of traditional screw
or expansion nail is inserted into an enclosed hole. Centering on the
hole, the screw or the nail will extrude the wall of the hole with the
same force at every direction. That is to say, centering on the screw
hole, the plate suffers uniform pressure at each direction, and because
of suffering the extrusion, the plate will expand in all direction. If
the quality material of the pate is thin or the expansion properties of
the plate are worse, the plate is easy to burst or damage. In the
invention, the screw 140 inserts into the screw hole 130, the screw 140
is partially contained in the gapped groove 150. Centering on the screw
hole 130, in the plate where the screw hole 130 is in, only the two side
walls of the gapped groove 150 are under pressure. That is to say, the
two side plate of the gapped groove 150 respectively suffer pressure in
opposite direction, because one end of the two side plate of the gapped
groove 150 is joint, the other end is not joint, it leads that the two
side plate of the gapped groove 150 expand in figure eight, thereby
avoiding the plate to burst or damage.

[0056] Preferably, referring to FIG. 1 and FIG. 5, the screw hole 130 is
trumpet-shaped. When the screw 140 inserts into the screw hole 130, the
screw cap 141 holds in the screw hole 130 and the screw body 142 holds in
the gapped groove 150, the two furniture parts jointed by the connecting
piece will connect tightly.

[0057] Preferably, referring to FIG. 8 and FIG. 9, the gapped groove 150
is located adjacent to the side surface 120 of the base 110. The wall 155
of the gapped groove 150, which is far from the side surface 120 of the
base 110, is perpendicular to the lower surface 111 of the base 110; the
wall 154a of the gapped groove 150, which is near to the side surface 120
of the base 110, has a lower portion inclining to the center of the
gapped groove 150. The gapped groove 150 is defined adjacent to the side
surface 120 of the base 110, thus the side surface 120 is easy to expand
for the extrusion from the screw 140. When the furniture connecting piece
installs into the reset recess cut in the furniture component, because of
the expansion of the side wall 120, the connecting piece more tightly
bites the reset recess cut in the furniture part, which increase the
joint strength between the furniture connecting piece and the furniture
component. Preferably, referring FIG. 8 and FIG. 9, The intersections 156
of the wall 154a and 155 with the gapped groove lower 152 is arc-shaped,
which increases the tension within the plate, makes the plate not easily
to burst.

[0058] Referring to FIG. 10, FIG. 11 and FIG. 12, the upper surface 121 of
the base 110 defines one or some recesses 114 extending to the lower
surface of the base. The recess 114 can hold a matching protruding post
on another furniture part, thereby matching the two connecting pieces.

[0059] Referring to FIG. 11, FIG. 13 and FIG. 14, when the recess 114 runs
into the lower surface 112 to form an opening in the lower surface 112,
the lower surface 112 sets a cover 116 to seal the opening. In the
invention, before the connecting piece installs into the preset recess
cut in the furniture part, first it is to coat the base 110 periphery
with glue, then install the connecting piece into the recess cut. It
depends on frictional force between the base 110 periphery and the wall
of the recess cut and the adhesive force of the glue to fix the base 110
and the furniture part. However, limited be the producing process, the
recess 114 embodies an opening at the lower surface 111 of the base.
During the installation, some glue will flows into the recess 114 from
the opening and occupy some place. When another protruding post matching
with the recess 114 inserts into the recess, there is not enough place
for the protruding post tightly joining with the recess 114.So, a cover
116 is set at the lower surface 111 of the base 1110, which seals the
opening of the recess on the lower surface 111, thus preventing the glue
flowing into the recess 114, and promising enough place in the recess,
then another protruding post matching with the recess 114 can insert into
the recess 114 and achieve tightly match to each other.

[0060] Referring to FIG. 15, FIG. 15 is a view of the fourth embodiment of
the furniture connecting piece in the invention. The screw 140 includes a
screw cap 141, a screw body 142 at one side of the screw cap and a screw
tongue 143 at the contrary side. In the figure, on the base 110 of the
connecting piece there is not protruding post. When the screw 140 is used
in conjunction with the connecting piece, the screw body 142 runs into
the screw hole 130 and holds in the gapped groove 150, the screw cap 141
holds in the screw hole 130, the screw tongue 143 inserts into another
suitable article. FIG. 15 shows that the screw tongue 143 is conical
shape, in actual using the screw tongue only need to insert another
suitable article that matches with it, its shape is not limited.

[0061] Referring to FIG. 16, FIG. 16 is a view of the fifth embodiment of
the furniture connecting piece in the invention. There is one or a few
glue tanks 116 which run into the front surface 111 and the lower surface
112 on the front surface 117 and the back surface 118 of the base. Before
the connecting piece is installed into the recess cut, a layer of glue is
first coated in the recess cut or on the periphery of the connecting
piece. After the connecting piece is installed into the recess cut, a
part of the glue will flow into the glue tank 116 and stays there, which
will increase the tightness of jointing between the recess and the
connecting piece.

[0062] Referring to FIG. 16 and FIG. 17, a notch 162 is provided on
somewhere close to the upper surface 111 at the relatively two surfaces
112 of the base. After the connecting piece installs into the mounting
groove, the screw 140 passes through the screw hole 130 and capacities in
the gapped groove 150, then it presses the side surface 112 to expand
outside, therefore, the side surface 112 bite with the mounting groove,
now, this may be drive somewhere close to the side wall at the upper
surface 111 to incline. The notch 162 relieves the effect of the
expansion of the side surface 112 on the upper side 111.
